LAMP-BURNER OR BURNER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 642,385, dated January 30, 1900.

Application filed March 26,1897. Serial No. 629,434. (No model.)

To all whom it may concern.-

Be it known that I, JOHN HENRY STONE, manufacturer, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Lamp-Burners or Burner At tachments, of which the following is a specification.

My invention relates to improvements in lamp and lantern burners or burner attachments; and the object of the invention is to increase the size and brilliancy of the flame without increasing the size of the wick, and yet not increase the amount of oil used for the given size of wick; and it consists,essentially,

of forming the wick-case of or attaching to it.

zinc and copper plates, with the zinc on the inside next the wick, the said plates extending into the bowl containing the kerosene.

Figure 1 is a sectional perspective view of a lamp and burner constructed in accordance with my invention. Fig. 2 is a longitudinal section through the burner and wick-tube shown in Fig. 1. Fig. 3 is a sectional perspective View of a tubular lantern, showing an alternative form of the invention. Fig. at is a longitudinal section through the burner shown in Fig. 3.

In the drawings like letters of reference indicate corresponding parts in each figure.

Ais the bowl of the lamp,and A the burner, which is screwed or otherwise fastened in the neck of the bowl in any suitable manner.

B is the wick-tube, which is made slotted, with a copper plate or tube O outside and a zinc plate D on the inside next the wick,which I designate E.

F is the oil,which is contained in the bowl A.

The flame produced is a clear white flame of increased size.

In Fig. 41 show the attachment in two parts B and B, having the zinc O on the inside and the copper D on the outside. It is of course an equivalent construction, and I may here state that the plates may be applied to or extend to or on any portion of the wick. In this instance the plates 0 are fastened underneath the burner A of an ordinary tubular lantern. The burner is surrounded bya cydisk at, which surrounds the wick-tube H.-

The upper portion of the burner A is formed in the usual manner. It is essential in the operation of my invention that such perforated plate a' be used in the lantern, although it is not usually necessary; but with my attachment it is used, as it distributes the air evenly in proximity to the flame, thereby preventing any danger of the draft blowing out such flame.

Although I describe in reference to Fig. 2 the plate B as attached to the burner, it will of course be understood that the wick-tube mightbe made in the same manner as in Fig. 1.

I find that by this construction I obtain an increased brilliancy and greater uniformity of flame with a given expenditure of oil as compared with lamps of this class heretofore used. This increase in the steadiness and brilliancy of the flame I conceive to be due to the effect of the sulfuric acid in the oil acting upon the copper and zinc plates and causing electrolytic action. Whatever be the mode of operation, the effect is as I have stated.

What I claim as my invention is- 1. The combination with a lamp having a bowl, a wick-tube and wick, a copper and zinc plate arranged adjacent to said wick and projecting into the oil-space in the bowl, substantially as described.

' 2. The combination with a lamp having a bowl, wick tube and wick, a zinc and copper plate arranged on opposite sides of the wick and projecting into the oil-space in the bowl, substantially as described.

3. The combination with a lamp having a bowl, a burner and wick, copper and zinc plates depending from said burner into the bowl adjacent to the wick, substantially as described.

JOHN HENRY STONE.
